System, method, and computer program product for reducing memory write operations using an instruction set

The present application claims priority to a first provisional application filed Nov. 24, 2006 under application Ser. No.: 60/860,843, and a second provisional application filed Jan. 3, 2007 under application Ser. No.: 60/878,242, which are incorporated by reference in their entirety for all purposes.

The present invention relates to memory, and more particularly to memory having a finite lifetime.

Memory is one of the most limiting aspects of performance of modern enterprise computing systems. One limiting aspect of memory is the fact that many types of memory exhibit a limited lifetime. For example, a lifetime of non-volatile memory such as flash is reduced, albeit a small amount, each time it is erased and re-written. Over time and thousands of erasures and re-writes, such flash memory may become less and less reliable.

Thus, depending on the type of use (e.g. light vs. heavy), a lifetime of flash memory may vary widely. This can be problematic in various respects. For instance, flash memory manufacturers are often expected to provide a limited warranty for a specified amount of time. While such warranty may be sufficient for light to typical use of the flash memory, it may require the return and replacement of the flash memory in instances of heavy use (e.g. in an enterprise application, etc.).

Such situations may significantly impact profits of a flash memory manufacturer. In particular, the need to continuously replace warranted flash memory for heavy-use customers can considerably reduce profits derived from the sale of flash memory to light-to-typical-use customers. There is thus a need for addressing these and/or other issues associated with the prior art.

An apparatus, method, and computer program product are provided for identifying write operations to be performed on a data stored in memory. Further, a difference is determined between results of the write operations and the data stored in the memory. In addition, the difference information associated with the difference is stored, using an instruction set. Furthermore, the write operations are reduced, utilizing the difference information.

FIG. 1 shows a method for delaying operations that reduce a lifetime of memory, in accordance with one embodiment.

FIG. 2 shows a technique for delaying operations that reduce a lifetime of memory, in accordance with another embodiment.

FIG. 3 shows a time interval-based technique for delaying operations that reduce a lifetime of memory, in accordance with yet another embodiment.

FIG. 4 shows an integration-based technique for delaying operations that reduce a lifetime of memory, in accordance with still yet another embodiment.

FIG. 5 illustrates a system for delaying operations that reduce a lifetime of memory, if a desired lifetime duration exceeds an estimated lifetime duration, in accordance with another embodiment.

FIG. 6 illustrates a method for delaying operations that reduce a lifetime of memory, if a desired lifetime duration exceeds an estimated lifetime duration, in accordance with another embodiment.

FIG. 7 shows a graphical user interface for gauging a lifetime of memory, in accordance with another embodiment.
